ABSTRACT The ever-increasng human population has necessitated the quest for an increase in food production in developing poor countries. In Nigeria, increase in fish production is increasingly driving the construction of artificial water-holding systems (ponds), which serve as breeding sites for mosquitoes. These mosquitoes are vectors of disease causing organisms like plasmodium and wucheria bancrofti. Here, this study focused on composition, abundance and diversity of mosquitoes utilising fish ponds in three selected areas in Benin City. Using standardised dippers for larvae collection, collected samples were taken to the laboratory for incubation until they emerged as adults. Upon emergence they were identified and counted accordingly. Observed data were subjected to analysis using PAST™. Result showed that 120 individuals of mosquitoes were encountered from 30 samples. Of these individuals, 73% were Culet quinquefasciatus and the least abundant species was Coquilletida spp. The nonparametric estimates for the average inventory completeness for 76% to 100% which suggests more species of mosquitoes could have been left unaccounted for. The implication of these findings is that it reveals the role of fish ponds in the proliferation of mosquitoes in the facility where they are found. Also, this could encourage the transmission of diseases such as malaria and Lymphatic filariasis
